Preheat an oven to 375 degrees F. Season the fillets on both sides with salt and pepper.
Place a large, non-stick saute pan over very high heat. When hot, add the oil, and swirl to coat bottom of pan. Brush each fillet (skin-side only) generously with butter.
Place the fish fillets into the hot pan, skin side down, and brown for 2 minutes over high heat. Place the pan in the oven for 3 minutes. Serve warm from the oven, with Chive Whipped Potatoes, Truffle Vinaigrette, and Sauteed Shiitakes.
Put the potatoes in a saucepot and cover with cold water. Add salt and bring to a boil. Cook the potatoes until tender, about 15 minutes. Strain the water out of the pot and mash the potatoes with the cream, butter, salt and pepper. Stir in the chive oil and sliced chives, and serve.

Place chicken stock in a saucepan and reduce liquid to 1/2 cup. Place chopped shallots in a large, stainless steel mixing bowl, pour hot stock over them, and steep for 10 minutes. Add the vinegar, season to taste, and slowly add the oils, whisking constantly to emulsify. Set aside until ready to use.
